Kink and fetishes are largely in the head. The cage is more a symbol and a toy to accentuate her control. What she really wants is me to be lusting for her, it brings her back to when we were dating in high school and I was a horny teenage boy courting her.
I agree to not come until she allows it. I could cheat, but if I did that would just be violating her trust and breaking what we have going on. I love and respect her, so I follow what she asks of me. Afterall, I did ask to bring chastity into our dynamic, so why would I destroy that?
With enclosed cages can get nasty. I like stainless steel that is more open (like with bars). Lather up, rinse off and you're good. I can also ask to be released for a shower and manscaping a couple times a week. We're sexually active 6/7 days a week so the cage comes on and off a good chunk of those times which can be opportunities to freshen the contents.
Got into chastity play so my wife usually gives me a week free to have sex and masterbate as much as possible. After that she asks me to lock up in a chastity cage. She has the key and so the only sexual contact I get is when she decides to unlock me and play. Usually it's a month without a full orgasm. She loves my lust for her and that I will go down on her, fuck her without an orgasm for myself and just generally want to please her. She and I both enjoy the power exchange and the pent up sexual energy. It really is a wild form of play that we started during the pandemic and we've kept it up because it is fun. It is so difficult to fuck her to orgasm without sending myself over the edge. She loves it!
That's just the flat cage, what about the dildo that attaches?
That you can just ask your partner if they would be interested taking part in something kinky... They may even want it or have thought about it.
